GAS AND OIL HEATING STOVE.

SPECIFICATION forming part of Letters Patent No. 251,185, dated December2?, 1881.

Application filed September 28, 1881. (No model.)

To all whom it may concern Be it known that we, WALTER CARSWELL andJAMES GEDNEY MILLER, both citizens of the United States, residing atGreen Bay, in the county of Brown and State of Wisconsin, have inventeda new and useful Gas and Oil Heating Stove, of which the followingisaspecification.

Our invention relates toimprovements in gas and oil heating stoves; andthe objects of our invention are, first, to provide a stovein which ,theheat is distributed over a large amount of jheating-surface, andutilizing the heat to a greater degree than the devices now in use,

' and, second, to provide exit-fines near the bottom of the stove, bywhich construction the heat is drawn downward to the base, making Weattain these objects by an arrangement of parts fully illustrated 201i!)the accompanying drawings, in which Figure l is aside elevation of ourstove; Fig. 2, a plan View; Fig. 3, a vertical and Fig. 4 a horizontalsectional view of the same.

Similar letters refer to similar parts throughout the several views.

The outer case of the stove consists of a cylinder, A, having the ends Band B, the whole resting upon the legs 6 c c 6.

Running through the center of the cylinder A, and secured to the ends BB, is the inside cylinder, E, provided with a series ot'projections ordampers, I), projecting alternately from opposite sides thereof abouttwo-thirds the distance across the diameter of said cylinder, forming abroken or irregular passage through out its length. (Indicated by arrows0.)

Situated inside of the stove, about half-way between the outer cylinder,A, and inner cylinder, E, and concentric therewith, is the annular flueO, secured to the bottom B, and extending to within about three inchesof the top B, forming a continuous passage from bottom to top of stove,around inside the outer cy linder, A, and thence downward from top tobottom around the inner cylinder, E, as indicated by the arrows at.

Near the bottom of the annular flue O are the exit flues or pipes H H,which pierce the outer cylinder, A, and connect with the re-' ceiver G,from which leads the pipe or chimney D.

Situated at the bottom of the stove, between the annular flue G and theouter cylinder, A, are the burners F F, (of which any number may beused,) of any suitable form, and connected with the supply in anyconvenient manner. The burners are readily accessible for lighting,cleaning, &c., by means of the doors d, one of which is placed oppositeeach for that purpose.

The bottom B is supplied with a number of perforations, (shown at t",Fig. 4,) which supply the necessary amount of oxygen to the burners torender the combustion complete.

The operation is as follows: The products of combustion from the burnersF ascend between the annular flue O and the outer cylinder, A, to thetop of the stove, where it accumulates to a certain extent, and thendescends around the inner cylinder, E, to the exit-fines H H, asindicated ,by the arrows at, from thence to the chimneyD, causing adraft, which removes any obnoxious odors which might arise from theburners and draws the heated air downward to the base of the stove, thusmaking a basearrows 0, through the irregular passage formed by theprojections b, and, becoming thoroughly heated, is em tted from the topand heats the apartment in which the stove isplaced by com vection.

It will be readily understood that the heat is also radiated from allsides of the outer cylinder, A, and the top B.

From the above description it will be evident that our stove is equallyadaptable to either gas or oil as a fuel, and in localities where thereare no gas worksor mains oil may be used and the stove be made to emitthe same amoun of heat as'with gas.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

1. In a base-heating gas or oil stove, the combination of the outercylinder, A, and inner cylinder, E, provided with projections b, withthe annular flue 0, having exits H H at or near the bottom,substantiallyas described.

2. In a gas and oil heating stove, the combination of the outercylinder, A, inner cylinder, E, and annular flue G with the burners flueO, exit-fines H, receiver G. pipe D, burn- F, whereby a continuouspassage or flue is ers F, and doors 07, substantially as described 1::formed which shall heat both of said c \linand shown, and for thepurpose set forth. ders at the same time, substantially as shown WALTEROARSWELL. and described. JAMES GEDNEY MILLER.

3. In a gas and oil heating stove, the com- Witnesses: bination of theouter cylinder, A, the inner SAML. D. HASTINGS, Jr., cylinder, E, havingprojections b, the annular OLIVER LIBBEY.
